' DIP PAINTING-EACHINE.

Specification of Letters Patent. Patented' Dc. 27, 1291.0. Application led October 7, 1909, Serial No. 521,517.

Y To all whom 'it may concern:

- other place where itmay be desired to de- Be it known that we, CHARLES VALLONE and FRANK R. ROGERS, citizens of the United States, residing'at Buffalo, in the county of- Erie and State of New York, have invented a new and useful Improvement in Di'p Paint ing-Machines, of-which the following is a specification'. y

This invention relates more particularly to improvements in dip painting machines of that sort in which the articles to be ainted, such, for example, as metal be stead frames, are hung on carriages ore carriers which travel on an elevated track provided with a vertically movable or elevating section which is arranged over a tank contain# ing paint and is adapted to be loweredwith the carrier thereon to immerse the article in t the -paint andto be again raised into position forl the carrier to move ofl" of the same onto a track leading towa drying room or liver lthe articles after being dipped. The

4improvements are not, however, `restricted in application to painting machines but are also applicable to machines or. apparatus used for other pur oses, where it is desired to provide means* or raising or lowering a traveling ycarrier from a track at one elevation to another elevation.

One of the objects of'the invention is to produce a practical and efficient dip painting machine which is capable of rapid operation and in which `the carrier, after the article has been placed thereon, is automatically moved onto the elevating track section, the track section lowered to immerse the article and returned to the initial position, and the .end elevation thereof. Fig. 6 1s a fra entary sectional elevation, on an enlarge scale, of the elevator and the o eratin device for the article carrier. Fig? is a fi'agmentary perspective View, on an enlarged scale, of the elevating track section and the latch for retaining the-article carrier thereon. Fig. l8 is a fragmentary elevation, partlyl in section, on an enlarged scale, showmg t e opposite side of the machine from that shown in Figs. 1 and 2.'

Like 4 reference characters refer to like parts in the severalgures. p

A A represent two stationary 'ortionsof an elevated or overhead track o any suitable construction, yandB represents a ver-- tically movable or elevating track sectionI which normally occupies a osition between the stationary ortions of t e track so as to, form therewit a continuous trackA lu on which carriers or carriages C are adapte to travel. The carriers may be of any suitable .construction enabling the articles to be read-- ily hung thereon. The track isarranged with the elevating section B located vertically over a tank or well (not shown) coni with the carrier and article hanging thereon.

embodying the invention, showing' the nori The stationary portions of the track are ,supported inany suitable manner, forV in stance, by hangers a and a depend1ngfrom` transverse beams a2, and other suitable overhead supports (not shown).

I respects hereinafter described 'and set forth The 'elevating track -section B vis lcarried by Aa suitable elevatoror hoist, which, in ,the construction shown, comprises a rod or lunger D having a laterally projectin goot' yto which the track vsection 1s secure A and which'is adapted vto reciprocate verf. tically'in a, stationarvguide consisting of antifriction rollers e, Fi 2, journaled in a opening in a platform supported on the 45 ythis character which is of simp e, stron and durable'construction, that can be readi y installed atl a comparatively small expense; and to improve dip painting machines in the 50 in 'the-claims. y In the accompanying drawings, consisting of three sheets: Figure 1 is a 'side elevation, partly'in section, of a dip painting machine beams 0.?, and a horizontal vplate b which is. supported byluprights rising from the platform 'and hasla guide opening through which vthe plungerl passes.

e3 representshangers suspended from' overhead beams andvx secured to the corners ofthe platform E for assisting in supporting the same. f

The plun er vD is raised and lowered by a chain F whlch is attached at one end to the lower end of the lunger, passes over-.a sprocket wheel suitably journaled on the platform E, an is attached at its opposite end toa cross bar G connecting two I'parallel endless driven sprocket chains H each of which passes aroundssprocket.v wheels h h h2 arranged to hold these chains in sub-V stantially 4triangular form. The sprocket wheels vJ1. and h are suitably journaled at different elevations on parallel frames h3 which may be constructed and supported in anyvsuitable manner. Between the sprocket wheels h and h theI frames ha are provided.

with guide bars h'i which are curved concentrically with the axis of the sprocket wheel i for the elevator chain F and on which rollers h5 at the ends of the cross bar G, connecting ,the driven. chains H H, travel. By:

reason of this arrangement of the parts, the

" driven chains H' H, asthey travel around the sprocket -wheels z, la.- h2 in the direction indicated by the arrows in Figs. l and'2, op-

erate through the chain F to raise the plunger D 'during the travel of the cross bar G from the sprocket wheels h2 to the sprocket wheels h', then hold it stationary in thel elevated .position withthe` elevating track secg tion B between the stationary portions of the track during the travel of the cross bar G over the curved guide rails h* between the sprocket wheels h and h', and then allow' the plunger lto descend by gravity during the travel of the cross bar from the sprocket wheels h to thesprocket wheels h?.

lz. represents idle sprocket wheels'which are suitablyjournaled on the frame h3 s othat'they can be adjusted for keeping the:

driven sprocket chains H taut. l

The chains H H may be drivenV by any suitable.v drive mechanism, forinstance, as*

shown inthe drawings, the two sprocket wheels/a,2 are secured to the inner ends of two horizontalshafts I I which are jouri naled in bearings i 'Z on the platform E a'd-V jacent .to the elevator or plunger D and are geared, for instance, by which j and j to a,.-

drive shaft J which is journale'd in vbearings on'the latform E and. is provided with a pulley y2 for a drive belt j, see Figs.l f1 and 2.

The article 'carriers or Acarriages C are i moved onto and off of the elevating track4 section during the period of time that the samev is heldv stationary between the stationaryportions of the track, by suitable hmechanism, whichas shown, is Aconstructed as follows: L, Figs. 6 and 8, represents a slide which reciprocates horizontally over the carrier' track on suitable guide'rails Z' which are secured to the bott-oms of the supporting beams a2. A rigid stop or finger Z depends from this slide and inrear of this rigid finger is a depending pushing linger Zgwhich 1s pivoted to the slide and is adapted toswing forwardly, but is prevented from swinging rearwardly beyond a vertical position by a stop Z3, Fig. 8, or other means. While the slide L is held stationary in Y its normal position by its' operating mechanism, a carrier C, on which one or more articles to be painted have been hung,

is rolled under the slide past the plvoted pushing finger Z2 against the stop finger Z, as shown in Fig. l, and the pivoted finger swings down by gravity behind the carrier C, vso that when the lide is moved forwardly thepushing linger l?2 will engage the carrier and roll it iforwardly along the track'onto the elevating track section. Z4 represents anotherrigid 'finger which depends from the slide L fore'ngaging theV carrierl C and shoving it ofi' of theelevating track section at the next forward movement of the slide.

The slide L is reciprocated, in themachine illustrated, byl means operated intermittently by the driven` sprocket chains H H, said meanscomprlsing a cam lever" naled on the upper portions of the supporting frames hfor the chains H H and nor- AM which is secured to a rock shaft fm, jou'rmally depends from said shaft in the path of the cross bar G, connecting the chains H H, as shown in Fig. 1.- The roek shaft m is provided with a rock arm m- 'conn eted by a rod m2 to a rock arm fnJ on a rock s aft N which is journaled on brackets projecting fromjthe platform E and is provided with a rock arm' n connected by a link n2 to the slide L. As the cross barvG, connecting the driven chains vH H, moves downwardly 4 along the curved guide bars hbetween the sprocket wheels .z/ and h2, it engagesthe cam lever M and swings the'same outwardly,

as shown in Fig.. E2, which, through 'the described connections, advances the slideA L,

land as the elevator is held stationary in its upper position dnring this time, as before explained, the sllde L is advanced at the proper time to move'the carrier which is on the elevating track section oil"l of the same and to -move another carrier onto the elep vating track section. A weighted arm -O- is shown on the rock shaft N which, as soon as' the cross bar G clears thelower end of the'cam lever M and frees the lever, drops by gravity` and retracts the slide -L yand re' turns' the vcam lever to their initial positions shown in' Fig. '1. The slide is retractedduring the travel of the cross bar. G'toward the elevator along the lower substantially horiz'ontal'limbs of the yendless sprocket chains osopo H H and consequently during the descentrof theelevator.

The elevating track section is provided i with a latch or y'd evice for holding the carrier thereon during the vertical movement of the track section. The latch shown, see

y'particularly Figs. 6-8, consistsof a pin P which is adapted to be projected upwardly through a hole in the elevating track section between the Wheels of the carrier C on the track section. The pin is connected at its lower end to one end of a lever' or plate p which is ivoted at its opposite end to the lower en of the plunger D. S rings `p connecting the latch lever p to stu s rojecting from the plunger, normally ten to lift the lever and project the upper end of the' p moves out of engagement with the stop Q and its springs immediately project the latch pin upwardly between the wheels of the carrier so as thereby to prevent the carrier vfrom rolling oil'l of the track section.

lWhen the elevating track section is againraisedinto the .normal position between the stationary portions of the track, the stop Q strikes the lever p and retracts the latch,

thus allowing the carrier to be shoved off of the elevating track section.

The operation of the machine is as follows: An article to be painted is hung on one of the carriers C on the track and the carrier is movedl under the slide L in front of the pushing finger Z2 and against the stop finger Z. The slide is advanced'by the de-` scrlbed ,mechanism and the carrier is pushed by the fin er Z2 onto the elevating track section B which lowers with the carrier and its article, immersing the latter inthe paint.

When the elevating track section commences the portion of the track the carrier on the track section.

to descend, the latch P is actuatedto hold The lelevating trackv section is then raised into place between the stationary portions of the track -and the latch is retracted. At. the next forward 'movement of the carrier moving slide, the finger l* thereof engagesand shoves the carrier oil"` of the elevatin track section onto leading to the dryfinger Z2 moves' another carrier,- which, in the vmeantime, has been moved into'position in front of said finger, onto the elevatin track section, ready t'o be lowered bythe e evator for immersing the article in the paint tank. It is only necessary for the operator to hang the articles into position to be engaged and actuated by the carrier -moving slide, W'hich can be done easily and with great ex edition.,

Oth'erwise, the l,machine is entire y automatic in its action. It runs' continuously and there are no starting and stopping or other devices requiring to be manipulated.

The several mechanisms described for moving the carriers onto and oil of the elevating track section while the latter i's stationary, for raising and lowering this track section, and for retaining the carriers on the elevating track section during the vertical movements thereof and releasing them when the track section is in its receivln and discharging position,'are etlicient an desirable and are therefore preferred, but mechanisms of other construction can be employed for performing these several functions Without yde arting from the scope of this invention.
